我有一个新的 Rails 应用程序启动并使用 Vagrant 运行，在 Vagrant 文件中将转发端口设置为 3000

config.vm.forward_port 3000, 3000

在我关闭服务器并退出 vagrant 后，我​​得到了这个输出“与 127.0.0.1 的连接关闭”，但是当我尝试在不使用 Vagrant 的情况下启动我的 Rails 应用程序时，它告诉我

谷歌搜索告诉我我应该这样做

ps ax | grep ruby

然后终止进程，但我被告知没有 grep 返回的数字的进程。 

michael$ ps ax | grep ruby
 3604 s001  R+     0:00.00 grep ruby
michael$ kill -9 3604
-bash: kill: (3604) - No such process

如果这与我对 Vagrant 的使用有关，知道如何解决这个问题吗？

更新

尝试lsof -wni tcp:3000在这个 SO answer 找到的命令TCPServer Error: Address already in use - bind(2)也未能终止进程

michael$ lsof -wni tcp:3000
COMMAND   PID                USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME

michael$ kill -9 PID
-bash: kill: PID: arguments must be process or job IDs
